  • Today’s refrigerators are 41% more efficient compared to those from 10 years ago
  • For every increase of 5°F above ambient temperature, your fridge uses 12.5% more energy

Author’s Final Thoughts

As interesting and fun as these facts are, there is an other concerning aspect to this – the quantity of fridges that are getting thrown out globally!

It is estimated that 53 million tonnes of electrical waste is thrown out every year, with that figure growing every year.

Not all that waste comes from fridges, but they are one of the largest contributors of the total weight sum. To put this into perspective, this equates to the weight of 350 cruise ships’ worth of electronics.

The solution may very well be running your existing fridge efficiently while maintaining it to extend its life expectancy before sending it to the skip.
